From Childhood to Capital Markets? Why Women Invest Less

Historically, the stock market was almost exclusively a male domain for decades. Photographs of the New York Stock Exchange trading floor from 1939 show an all-male scene. Today, the presence of women in international financial centers has visibly changed. However, legal equality has not led to actual equality in investment behavior.

The gender investment gap

To this day, significant gender-specific differences persist in wealth accumulation. Prof. Dr. Alexandra Niessen-Ruenzi, Chair of Corporate Governance at the University of Mannheim, together with co-authors, analyzed in a study why women, despite formal equality, remain significantly less active in the capital markets and what decisive role early financial socialization plays in the emergence of this so-called gender investment gap.

The existence of this gap has been proven: Based on a representative survey of 2,132 participants, the researchers identified a difference of 14.6 percentage points in stock market participation, with only 17.7% of women investing in stocks, ETFs, or mutual funds compared to 32.2% of men.

A key finding of the study is that this gap remains statistically significant even when factors such as education and income are taken into account. This reluctance among women to participate in the stock market must be viewed critically: Given that women face a 25% higher risk of poverty in old age, participation in the stock market—which offers significantly higher average returns than conservative investment models—is not an option but an economic necessity. Women are forgoing potential gains if they do not take advantage of the stock market for themselves and their investments.

The roots lie in the family home

According to the study, the roots of this behavior lie in financial socialization within the family home and the associated economic preferences. In German households, financial topics are systematically discussed less frequently with daughters than with sons. While only about a quarter of daughters report that their parents actively discussed finances with them, sons show significantly greater involvement. 

Since finance is often traditionally perceived as a male topic, girls receive fewer early stimuli, which inhibits the development of an investment-oriented identity.

Knowledge gaps and psychological barriers

These deficits in socialization result in measurable knowledge gaps and psychological barriers. When tested on the so-called Big Three of financial literacy—understanding compound interest, the effect of inflation on purchasing power, and the importance of risk diversification—women consistently perform worse. 

Particularly concerning is the gap regarding diversification, i.e., spreading risk across different asset classes. Here, only 49.9% of women knew the correct answer, compared to 64.6% of men.

Another key finding in behavioral economics is the difference in levels of self-confidence. While men often exhibit a so-called overconfidence effect—meaning they are frequently convinced of the correctness of their answer, even when it is wrong—women tend to have significantly lower self-confidence when it comes to financial matters. Even when they actually possess the knowledge, they are more likely to choose the “Don’t know” answer option. This creates a significant barrier to market participation.

How role models and networks shape investment behavior

In addition to the family home, role models and social networks also shape how individuals engage with the stock market. Men are more likely to look to external experts or prominent investors such as Warren Buffett or Elon Musk, making them less dependent on socialization within the family environment.

Women, on the other hand, primarily cite people from their immediate circle, such as fathers, mothers, or partners. The lack of informal information channels within women’s peer networks creates a structural barrier. Since women are less likely to have friends or colleagues who are interested in investing—38.4% of women compared to 51.2% of men—they lack the social interaction that could facilitate entry into the stock market.

How We Can Close the Gap

To close the gender investment gap in the long term, the authors of the study recommend implementing the following:

  • Embed financial education in schools to break down traditional gender roles;
  • Actively involve girls in financial decision-making processes;
  • Promote female role models to strengthen financial self-confidence.

Only through independent and well-founded financial education can we ensure that women independently take advantage of the opportunities offered by the capital market to minimize the risk of poverty in old age and achieve long-term financial independence.
